THOMAS DAUGHERTY, OF ERIE, PENNSYLVANIA.

LASTING INSTRUMENT.

Speccation of Letters Patent No. 11,453, dated August 1,` 1854.

To all whom, I? may concern.'

Be it known that I, THOMAS Dauer-mary, of the city of Erie, in the county of Erie and State of Pennsylvania, have invented a new and useful Machine for Lasting Boots; and

I hereby declare the following to be a full and `clear descriptionthereof, referenceV being had to the drawings herewith presented,

which drawings constitute a part of said del by one screw they are both closed and drawn together, at the same time and the jaws of the instrument stand on one side so as to give ample room for the body of the awl or hammer as it passes over the jaws in piercing the hole`or driving the peg.

See the drawings. The figure is an isometrical view of the machine.

J and J, shows the jaws as they project above the Shanks of the levers Land L. At T may be seen a nut movable on the screw S. Now the short levers B and B, are continuations of the inner jaws of the pincers; the knob Gr is a fixed shoulder on the screw S'. It may be seen that when the screw is turned the nut` T advancing toward Gr brings the jaws toward each other while it pressesV them tight together stretching the Then by tipping the instrument back on the heel of the lever the leather is drawn into any proper and desirable shape. The jaws being on one side of the levers allows perfect freedom of action in securing the uppers; there is an advantage in the particular form of the levers forming as they do the handles and jaws of the pincers, and its heel forming the fulcrum over whichto pry up and raise the entire jaws clear from the surface of the sole.

My object in formingthe lower part of my machine as described is to avoid the diiii- `culty that occurs with other machines.

Vhen a tack or peg is driven to secure the leather it is important to have its point standing a little out-ward to prevent its being drawn out, or the leather being drawn off. This cannot be done with the old machines which take both outside and lining for when drawn up they stand in the way of putting in the tack or peg. This is a serious objection to using those machines, and this difliculty I have remedied by having the jaws on one side and at the same time I take bot-h outside and lining.

I do not claim the invention of pincers, levers, screws or any of the parts separately of this machine.

Vhat I claim as my invention and desire to secure by Letters Patent is- So constructing the machine as above de-` scribed that when drawn up I have ample room for putting in the tacks or pegs and having heel which serves as a fulcrum so that by pressing back the top of the machine I am able to raise the entire jaw clear of the sole and' prevent the jaws from ruttling up the inner sole.

In testimony whereof I hereto subscribe
